Measles is one of the most contagious viruses in the world, but why? In this episode of Plugged In to Public Health, host Maxwell Hanson talks with Dr. Patrick Sinn, a pediatric pulmonologist and researcher at the University of Iowa, whose work has reshaped how scientists understand measles transmission. Dr. Sinn’s lab made a surprising discovery that challenged decades of assumptions about how the virus infects airway cells, revealing new insights into why measles spreads so efficiently. Together, they explore what makes measles different from other respiratory viruses, how vaccine hesitancy has fueled recent outbreaks, and why effective communication remains a cornerstone of public health. Dr. Sinn also shares how moments of unexpected results in research can lead to major scientific breakthroughs.
